Hello everyone, I just booked our family's first Celebrity cruise. We have a wait until our cruise in December, but I was browsing some of the excursions and was surprised to see one was sold out already. I was wondering how far in advance you would advise to book excursions? I had thought I might wait until the week of the cruise so I would know more about the weather situation but don't want to risk things being sold out. Thanks :)
